CHECK-ROW ER FOR CORN-PLANTERS.

SPECIFICATION formingpart of Letters Application filed December 10, F83. Renewed Fe 1 0 all whom it may concern.-

Be it known that I, JOHN KAYLOR, a citizen the county of Macon and Stateof Illinois, have invented certain new and useful Improvements inCorn-Planter Check-Rowers, of which the following is a specification. Y

My present invention relates to improve,

sists in an improved construction of frame on improved lock for thecheck-row rock-shaft, improved means for transmitting motion from animproved construction of the forked lever which actuates the rock-shaft,and improve ments in the attaching-brackets, and otherimproven ents, allas hereinafter more fully described, and specially designated in theclaims hereto annexed. l

In the accompanying drawings, which illustrate one method of applying myinvention Figure 1 is a top plan of the frame and attachments; Fig. 2, asectional elevation in the line a: x in Fig. 1, and an elevation of themechanism fortransmitting motion from the rock- Fig. 3, a sectionalelevation of the parts shown shaft; Fig. 4, a side elevation of theclamp and bracket used in the construction of my cheekrow frame and inattaching it to the planter, and also shows the frame-barsin section;Fig.

Referring to the drawings by letters, the same letter indicating thesame part in the dif ferent figures, A A represent the heads, used ateach end of my improved frame, to furnish bearings for the rock-shaftfor the ordinary pulleys to guide the check-row line, and for the pawlto limit the motion of the check'row shaft.

Patent No. 344,116, dated June 22, 1886.

bruary 1, 1886. Serial No. 190,556. (No model.)

My improved frame, on which the checkrow devices aremounted, is formedof bars or rods B B, secured together, as hereinafter described.

C is the check-row rock-shaft, provided with bearings in the main frame,and otherwise in termediately supported.

D is a bracket formed of clamp-plates d d, located on the bars B, andelampplates d d, located beneath said bars, and all held securely onsaid bars by bolts andnuts 61.

E is a bevel pinion fixed on the rock-shaft G, and has a concave face onits toothed side.

F is abracket secured by clamps and bolts 9 on the'bars B, as shown inFig. 5. Arms F project downwardly from the bracket F.

G G are the end pieces of my improved frame, each of which consists of aclamp, b, located above the bars B, and a clamp, 12, lo-

cated beneath them. The clamps b b are se- :curedto the bars B by abolt, 5, and the 'has trunnions 2'? near its mid-length portion,

by which it is journaled in the pendants F. The arm i is adjustable in aslot at the lower end of thelever i, as shown at Fig. 5.

In operation the pinion E is moved by the forked lever at each impulsereceived therefrom to that extent which will give asemi-rotation to thepinion e, which will in turn,through the crank-wheel rod k and lever 13,impart movement to the seed-slides of the planter, each throw of theforked lever giving a throw to the lever i.

To prevent backward movement of the rockshaft, that part of the shaft ofpinion e designated by the letter h in Fig. 2 is formed square in itscross-section and carries a ratchetplate, h, which has free verticalsliding motion on said shaft,and which forms a look after each motion ofthe shaft and gearing by dropping behind the projection d on the part 12of bracket D.

The forked lever a is formed of two parts, i

series of parallel bars, B, brackets b, clamps an upper forked. end part(designated by the letter a) hinged to a lower part, a where indicatedby the dotted lines a. The part a is pivoted on the rock-shaft O. Aspring, a, is connected with a downward extension. from the part a ofthe forked lever,to return said lever after each backward throw given,it by the tappets on a check-row line in the ordinary manner. The-upperpart of the forked lever is provided with curved projections n a, one ofwhich, n, is provided with a projection that engages with the teeth of aratchet, m,

other, n, by coming in contact with the circular portion of a, limitsthe hinge motion of a on a while. the same is being returned by thespring to its normal position after a stroke has been efi'ected bycontact of the forked leyer with a tappet on the check-row line.

Thepawl (indicated by letter Z)-is represented as being held out of;contact with ratchet m by a lateral projection on the part a; but at thetermination of'every stroke of the forked-lever,

produced; by the check-row line, the pawll slides off said projection,and; is thereby, permitted tocome in contact with the ratchet m andeffect aflock, both of said ratchet and the rock-shaft G.

I. prefer to useclamps, as shown in the drawings, for securing theattachments to the bars B, except where greater rigidity is desired, asat'g gin Fig. 2

The. construction herein shown and described of the frame on which thecheck-row devices are mounted is simple, durable, and 1 I 1 looselymounted thereonand adapted to act on a ratchet fixed to the rock-shaft,the. pinion E,

furnishes a frame which is very strong, and to which the attachmentsare] not only simply and easily attached, but on which they are easilyadjustable by moving them on the bars B, and securing them, after thedesired adjustment is efi'ected, by means of the clamps and bindingscrews. space between the bars B affords a strong so p; on; for theattachmentsand makes it possible to sustain the same. centrally, asshown.

Any desired number of bars B may be used.

Having thus described my invention, what I l i gnejw, and desire.tosecure by Letters Patent, is
